Georgia GOP district chairman: Baseball practice shooting will win us the election

The most recent polls show the race - seen as a key indicator for next year's mid-term elections - virtually deadlocked as both candidates sprinted to the finish. With questions swirling around ongoing investigations into whether the Trump campaign colluded with Russian Federation and the lack of major legislative accomplishments, many pundits believe an Ossoff win could panic Republicans into thinking their current approach isn't working.

With a price tag of more than $50 million, both parties are using the House seat as a barometer to gauge their political power in the age of Trump.

That meant nobody who registered after March 20-90 days before the runoff election-could vote in the hotly contested Ossoff-Handel race. The GOP already has won House special elections in Montana and Kansas, and the Republican is favored in a SC race Tuesday.

Both parties have spent more than $56 million on the special election, making it the most expensive congressional race in USA history, easily surpassing the 2012 election in Florida's 18th, which cost $29.5 million, according to the Center for Responsive Politics. "I think it's disgraceful to politicize it, and I think Secretary Handel should call for it to come down", Ossof told reporters.

The two campaigns and political groups have bombarded Atlanta airwaves with election advertising.

The Democrat Congressional Campaign Committee says it has spent more than $6 million "to fundamentally transform a traditionally Republican electorate, turn out low-propensity voters, channel the unprecedented grassroots energy, and communicate with swing voters".

Some observers were also eying the race for clues into how voters perceive the Republican health care bill now making its way through Congress.

What time are the polls open?

If Democrats win, they'll likely portray the result as a good sign for their chances of taking control of the House, now controlled by Republicans 238-193.

The president is tweeting about Ossoff and his Republican opponent, Karen Handel, a day ahead of their matchup that is billed as a preview of the 2018 midterms.

Door-to-door canvassing and a months-long advertising blitz in the most expensive congressional election in US history - over $40 million spent on TV commercials alone - appear to have succeeded in maintaining intense interest in the election, seen as a test of Trump's popularity and Democrats' potential to win the House in 2018.
